The postdigital era has arrived where digital has been integrated as an everyday culture and it is no longer sufficient to conceive of art museum experiences as soley onsite events. To reconceptualize art museum education in the postdigital era, this study compares the ‘pervasive art museum’ model with the ‘online art museum’ and the ‘distributed art museum’ models. Furthermore, the pedagogical possibilities of networked digital images are explored and reintroduces art museum learning as a decentralized network effect of human and non-human actors. For this multiple case study research, three cases were selected using maximum variation purposeful sampling. The cases are discussed under the following three key words: 1) rearrangement of time and space, 2) shifting centers of authority, and 3) emergence of new learning network through translation. Based on the cross-analysis of the three cases, this study proposes three issues of art museum education in the postdigital era as follows: 1) rethinking art museum’s positionality, 2) the necessity of onsite and online practices, and 3) accessibility. In conclusion, this study aims to expand upon existing discussions of art museum education by tracing postdigital-related discourses and suggests that art museum education practices incorporating online experiences should continue while highlighting its necessity other than the reason of lockdown.
